I have a photo diode with me and a ir led , can I use a tv remote for controlling a LED, If then how ??

Here you go photodiode

If your goal is to use a photo diode to interpret the coded signals sent from a tv remote control, then you will have difficulty. Google for 'TSOP4838 arduino' to see possible solutions.
If you simply want to detect that the remote control is active, and it is near enough, you may be able to use the photo diode to detect something.
If you are experimenting, start with your IR led and the photo diode. Google for possible circuits.

The best approach is to use an IR receiver.

However the following may be of assistance:
